QM-5 Mantle, Glas-Col® Spherical-Style, O-Ring

This mantle is a spherical style, which covers both top and bottom of 1-, 2-, or 3-neck spherical flasks for improved safety and efficiency. The circumferential zipper holds the halves snugly together to prevent heat loss, and the side split in top allows removal without disturbing the flask. Mantle should be used with Series 0 supports. All mantles are 115 Volt.
